Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), and the description usefully adds the mechanism of the result: the resume text is carried in the URL #fragment and never sent to a server. This privacy detail is real added value, though nothing is said about length limits despite a 30000-char cap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, the action front-loaded and the privacy note second. No filler or restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly explains that the result is a link the user opens elsewhere, and the fragment/server clarification answers the obvious agent question. Minor gaps (what to do with the link, size limits) remain but aren't blocking.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

One parameter at 100% schema coverage, so the schema already documents resume_text fully, including its line-based plain-text format. The description reinforces how the text is conveyed (via the link fragment) but adds no formatting or constraint detail beyond the schema — baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb and resource — 'Make a link that opens this resume in ATSPrep Studio' — and clarifies the deliverable (an editor link, not an edit itself). This clearly distinguishes it from siblings like check_resume, tailor_resume, or list_templates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The purpose clause ('so the user can fix it, pick a template and download a PDF') implies this is the hand-off step after producing a resume, but it never states when to choose this over alternatives or any preconditions. Usage is implied rather than specified.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
